To all whom it may concern Be it known that I, ANDREW M. AnnemsoN, a citizen of the United States, and a resident of Mbscow, inthe county of Latah and State of Idaho, have invented a new anduseful Improvement in Threshing-Ma,- chines, of which the following is a specification.

My invention is an improvement in thresh ing machines, and hasfor its object the provision of a machine of the character specified, wherein means is provided for removing the heads from the stalk and forhushing the grain immediately after the heads are separated.

A. further object is to provide other mechanism. for separating t e grain from the chaff, and for delivering the grain and the chaff separately from the machine.

In the drawings:-Fignre 1 is a. front View of the improved machine, Fig. 2' is a top plan view, with parts omitted for the sake of clearnessi Fig. 3 is a side view with parts insection, Figs. 4 and 5 are sections on the lines 4-4. and 5--5 respectively of Fig. 1, Fig. 6' is a partial vertical section ofene of the cylinders, Figs. 7 and 8 are sections on the lines 7-7 and 8-8 respectively of Fig. 6, Fig. 9 is a section on the line 99 of Fig. 7, Fig. 10 is a perspective view of the connection between the cylinder operating shaft and the draper operating mechanism.

The present embodiment of the invention comprises a substantially triangular frame 1, having at its apex a. steering. device to be described, and having at the front a substantially rectangular extension. 2, in which the harvesting and threshing mechanism is mounted for vertical movement. The body 3 of a yoke isiournaled at the apex of the frame 1 in a bearing 4 and a: wheel 5 is jeurneled between the arms 6 of the yoke. A peripherally grooved segment 7 is secared to the yoke above the wheel, and the ends of a chain 8 are secured to the opposite sides of the segment as shown at 7 and the body extends forwardly and is engaged with a. ulley 10 secured to the lower end of a she-ff 11,-journaled in. the frame and having at its upper end a hand wheel 12 for convenience in turnin thesame. The chains adjacent to the pn le 10 ass over a double pulley 10- journale on; t e frame.

55, By means of the hand wheel the plane of the wheel 5 mar be changed to guide the frame through t field. The front or base of the frame is supported by wheels 13,.

which are secured to the ends of an axle 14, ournale'd in the extension 2. A motor :14 of suitable construction as for instance,

an explosion-engine, is supported: on a latform 15 at approximately the center 0 the frame 1, and the shaft 16 of the engine extends forwardly intoa housing 17. The shaft or axle 14 is divided, the inner ends thereof extending into: the housing 17 where any suitable connecting mechanism is arranged for connecting the said innerends with the forward end of the shaft 16. A shaft 18 is journaled in bearings 19 on the frame 1, and a drum 20is journa1led: loosely on the shaft. A clutch 21 is provided for connecting the drums with the shaft, and the shaft is driven from the engine 14 in any suitable manner.

An auxiliary ame 22 is mounted for vertical sliding movement in the extension 2 and cords or cables are connected with the auxiliary frame, the said cords passing upwardly over the rollers or pulleys 24 at the corners of the extension, and hence inwardly and downwardly over pulleys or rollers 25,. and hence rearwardly over other pulleys to wind upon the drum- When the drum is clutched to the shaft, the drum will be rotated to raise the auxiliary frame in the extension A sprocket wheel 26 is secured. to the shaft 18, and a chain 27 conwith a. bevel gear, 32 on the outer section 33. "of a telescoping shaft, whose inner section' 34 is slidable in the outer section and is splined thereto as shown at 35 in gig. 5, and the said inner section is provide at its lower end with a bevel gear 36.

The lower end of the inner section 34 is jonrnaled in abearing 37 having arms 38 provided with bearings, which engage a sh ift 39 'purnaled in bearings 40 on the upper en .of the auxiliary frame. The shaft 39 is provided at regular intervals with bevel pinions 41, each of which meshes with a. bevel gear 42on the shaft 43 'of a cylinder to be described. I

The telescoping shaft 33-34 insures a driving connection between the shafts 29 and 39, regardless of their relative position with regard to each other. When the auxiliary frame is lifted, the inner section 34 of the shaft slides inwardly in the outer section 33.

As. many cylinders may be provided as may be desired, and each cylinder coiiperates with the concave 44. Each cylinder (Figs. 6 and 7) consists of a drum 45, connected to the shaft 43 by means of castings 46, each of which is connected to the drum by means of bolts or rivets 47, and to the shaft by means of bolts and nuts 48. The outer face of each drum is provided with a plurality of peripheral projections 49, the

. drum being pressed to form the said projections, and the said projections are arranged with their bases in contact. Each of the concaves 44 consists of a plate arched transversely, and shaped so that the concave surface is provided with peripheral projections 50, corresponding to the projections 49.

The concave is shaped on an arc whose center is the shaft 43 and is arranged with respect to the cylinder, so that the projections' 49 just miss the projections 50. The upper end of the concave is bolted to the auxiliary frame 22 as shown at 51, and an are shaped shield or hood 52 is arranged on the opposite side of the cylinder from the concave, the adjacent edges of the concave and the shield being spaced apart as shown in Fig. 7 to permit. the entrance of the grain.

The shield or 'hood is bolted to the auxiliary frame 22 as shown at 53, and at the front edge of the shield dividing fingers are provided, each of the said fingers consisting .of two planes 54 and 54, connected at their outer edges and diverging at their inner edges, one of the said lanes 54 having its inner edge connected with the front edge of the shield 52. v

A feed roller in the shape of a drum 55 is journaled at the forward end of each concave in bearings 56 on the auxiliary frame, and the inner edge of each lane54' is arranged adjacent to the perip ery of the said roller. The planes 54 and 54 are trian lar in form as shown more particularly in igs. 3- and 4, and the apices of the planes are arranged forwardly. The said fingers separate the grain into lots or bundles of a size such that one cylinder can take care of the saidlots. The. said walls of the adjacent fingers that is, 'the planes 54 and 54" converge toward their inner ends and condense coneave, breaking theheads and separating the grain from t e husks.

A cutting blade or disk 56 is arranged at the lower end of each cylinder 45 for severing the heads from the stalks and each of the rollers 55 is rotated by means of a pinion 57 secured to the upper end of the shaft of the roller and meshing with a gear wheel 58 on the shaft 43. Each of the shafts 43 is journaled at its ends as shown in Figs. 8 and 9, the upper end of the said shaft being journaled in a cup-shaped housing .59 ha\' ing an opening in its lower end for receiving the shaft, and a roller bearing 60 is arranged between the shaft and the side wall of the housing.

A cover 61 is provided for the upper end of the bearing, the said cover also having an opening for receiving the shaft. The lower end of the shaft 43 is also received in a cup-shaped bearin 62, and a roller bearing 63 is arranged etween the shaft and the side wall of the bearing. The lower end of the shaft 43 is recessed as is also the inner face of the lower end of the bearing 62, and a ball 64 is arranged in the registering recesses. The upper end of the bearing 62 is flanged laterally as shown at 65 and a cover 66 havin a centrally perforated boss 67 fits within t e upper end of the bearing, covering the said bearing, the shaft passing through the boss.

The lower end-of the bearing is provided with a central enlargement 68 which fits within a similarly shaped recess 69 in the frame. The upper end of the bearing 59 is flanged laterally as shown at 70, and the said flange is secured by bolts 74 to a flange 71 on the cover 61, and. the bearing 59 is .provided with lateral flanges 72, WhlCh are secured to the auxiliary frame 22 by bolts 73.

understood that all of the cylinders are similarly mounted.

The grain passes from between the cylinders and the concaves to a draper or endless .belt75, supported by rollers 7 6'journaled in the auxiliary frame, with its u per run immediately below the blades or disk's 56. The grain falls on the upper run of the draper and passes to the right of Fig. 1, and is delivered to the upper run of a second draper 77 supported by one of the rollers 76 and .a roller 78, the latter roller bein journaled at the upper end of an elevator iox or casing 79. The lower run. of a second draper or endless belt 80 coiiperates with the upper run of the belt or dra er 77 to lift the grain, and each of the t ree diapers-7 5, 77 and 80 is provided with transverse slats 81 for assistin in moving the grain. The u 1 per end 0 the elevator ormed by t e drapers 77 and 80 delivers'to a hopper 82, arranged on an extension 83 of the extension frame 2. The draper 80 is supported-by -lower and upper rollers 83 and 84 respec- Lin-,6

t0 The inner end' of the. roller 88 is pro vided with-a sprocket wheel 111, connected by a, sprocket chain 112', with a sprocket wheel 113 onthe shaft 29 before mentioned. The roller 88 'is thus driven and in turn he drives the roller 89, the-shaft 100 and the fan 106.

Thedrapcr75 forms the bottom of a receptacle having' arear wall 114., the front well being formed-by the cylinders and conto caves.

p The aiary heme 22 may be raised or lowered in accordance with the height of the grain to-be out; It will bra-understood that hutlittlemore an the head ot the grain is W removed. The auxiliary frame is raised or dly by the conveyor and is varranged between the outer face of the said fed or belts 7780 and the elevator del vers the lowered'by meansof the drum 20' and the height at which the frame stands is under the control'of the operator atthe engine 14.

The operator also guides the frame by means of the wheel 5, and as the machine moves 75 through the field, the stalks are separated by. the fingers and each row or division between ad'acent fingers is condensed-and fed by the ro er 55 to the adjacent cylinder and concave.

The auxiliary frame engages the extension frame 2 at the front of'the said frame as shown more particularly in Fi 6 and 7. Each of the front members 0 the exten sion frame is T-shaped in cross-sectionas shown at 115 in Fig. 7, and the auxiliary frame is provided with id'eways for receiving the cross member of the T. The idewa s are formed by a proximatel -sha e plates 116, secured $0 the auki -i iary ame by bolts 117. A series of rollers I18'is arranged between the inner face-of the cross member of the T and the auxiliary frame, and other series 119 of rollers are 96 cross member and the adjacent plat'e'1I6. The series 119 are heldin place by inwardly extendin flan es 120 on the. zvshaped plates. ith t is construction, the auxiliary frame may move freely vertic'all on as :the extension frame in accordance with the hei ht of the grain tobe cut.

he outer end of the shaft 39 is rovided with a pinion 121 (Fi 10) whic meshes with a pinion 122 on th t} stub shaft 123,.se cured to the auxiliary frame 22. A pulley 124 rigid with the pmion 122 is also journaled on the shaft and a belt 125 connects 'the said pulley with a pulley'126 on the adjacent lower when 76 of the dra er. The draper is thus operated from the s aft 39.
